Title: Flash lamp and core of end cap thereof
Inventor: ANSONII MAGURIKA
IPC: F21L19/00
Filed: 1990-05-16
Abstract: PURPOSE: To provide a flashlight equipped with a tail cap core for ensuring electrical connection between a battery and a flashlight body, by providing the tail cap core with a spring connected to the battery and a tail cap. CONSTITUTION: In an assembled state of a flashlight, a tail cap 24 is threadedly attached to a rear end part of a main barrel 22. Because compressive force generated in an energizing spring 28 by coaction of a battery 56 and the tail cap 24, is exerted on a contact piece 14 to expand the contact piece 14 outwardly in the radial direction, the contact piece 14 makes secure contact with an inner circumferential surface of a cavity 36 in the main barrel 22 to achieve electrical connection. Because a spare-bulb holding part 38 of the contact piece 14 simultaneously exerts force acting inwardly in the radial direction on a spare bulb 50, the spare bulb 50 housed within an insert 10 is held securely in a center hole in the tail cap 24.

Title: D.c. motor speed controller
Inventor: WAKITA YONERIKI
IPC: H02P7/06
Filed: 1978-10-18
Abstract: PURPOSE: To control a speed increase in a d.c. motor at quick increase in power voltage, by magnetically coupling a shunt reactor and a smoothing reactor which is in series with the armature winding.  
     CONSTITUTION: Amarture winding Ma is connected in series with a smoothing reactor L1 which controls rise up of rush current into the armature winding Ma. Output from the auxiliary generator E x  is connected through the adjusting units CRf and the shunt reactor L2 to the series-wound field winding MF. The smoothing reactor L1 and the shunt reactor L2 are magnetically coupled, so that when rush current passes in the amarture winding Ma, field current in the series-wound field winding MF is increased by an electromotive force induced in the shunt reactor L2 by mutual induction action with the smoothing reactor L1. This strengthens the magnetic field in the motor M and increases counter-electromotive force in the armature Ma, resulting in controlled increase in rotation speed to bring it back to the specified value.

Abstract: PURPOSE:To enable prevention of deterioration of characteristics of a base by a method wherein the terminal of each of grooves made in the shape of a lattice from the surface of a semiconductor wafer to a depth beyond a P-N junction is so provided as to project from the part of intersection with another groove. CONSTITUTION:Every time when one P-N junction is formed, grooves are made in the shape of a lattice from the surface of a wafer to a depth beyond the P-N junction, and the terminal of each of the grooves 2 and 3 is so provided as to project from the point of intersection with another groove. Even with respect to the outermost ones 1A out of the semiconductor bases formed in the shape of the lattice, accordingly, two of the grooves 2 always intersect each other, and when the wafer is cut along these grooves 2 by a dicer, it is prevented that cutting is made from a grooved part through a part not grooved or from the part not grooved through the grooved part in the periphery of each of the outermost semiconductor bases 1A. By this method, a stress applied to the wafer 10 is reduced and it is avoided that deterioration of characteristics of the semiconductor bases 1A is caused by a mechanical damage.

Filed: 1976-10-27
Abstract: PURPOSE:To maintain the same advantages of a light modulator as those of the conventional one by allowing the modulator to be very easily fabricated by arranging 3dB coupler formed, for example, of three rectilinear light wave guides linearly with a phase shift section formed of electrooptical substance and substantially parallel light wave guides.
Patent JP-S6019938-A (JP)
Title: Fuel injector
Inventor: NAKAGAWA TOYOAKI
IPC: F02D41/20
Filed: 1983-07-14
Abstract: PURPOSE:To enable the proper operation of a solenoid valve under low electric power and lengthen the life of the valve, by decreasing a voltage applied to the solenoid of the valve, while maintaining a prescribed magnetic force caused by the solenoid, after closing the solenoid valve, to reduce a drive current while keeping the force closing the valve. CONSTITUTION:When a solenoid valve 42 is closed, the gap between the magnetic poles of an armature 51 secured on a valve-acting element 47 and a core 52 fitted with a solenoid 53 is made very small, so that the attractive magnetic force between the armature and the core is made much stronger than that at the beginning of the closure of the valve 42. For that reason, an enough closing force for the solenoid valve 42 is maintained even if the voltage across the solenoid 53 is dropped to a certain degree after the closure of the valve. At the time of the drop of the voltage, the output level of a comparator becomes low, and is kept low until a signal from a control circuit changes to a low level. At the time of the change of the signal to the low level, a switch is turned off to stop supplying electricity to the solenoid 53, and an RS flip-flop is put out of action by a signal from an inverter to open the solenoid valve 42. The quantity of supplied electricity is thus decreased in the closure of the valve 42 to enable its proper operation under low electric power.

Title: Magnetic card and its production
Inventor: SATO SHINJI
IPC: G11B5/80
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic card capable of preventing vicious forgery and alternation actions, such as the action to make the magnetic card reusable by renewing the magnetic recording area of the magnetic card with the magnetic film part of the unused area exclusive of this magnetic recording area. SOLUTION: This magnetic card is formed by laminating a magnetic layer 2 which records and reproduces information and a magnetic shielding layer 3 which consists of high permeable magnetic powder by orienting these layers to align the axes of easy magnetization in an intra-surface direction. The high permeable magnetic powder in the magnetic shielding layer 3 is partly disturbed in the orientation, by which a non-oriented part 3c of a nonuniform direction or a perpendicularly oriented part 3b directed to a perpendicular direction is formed. This oriented part is thus put to the state of the noise and output level higher than those of the oriented part 3, by which the reuse is prevented.
